To all'whom it me concern:

Be it known 1:

V 'Brockport, in the county of Monroe and State of New York, haveinvented certain new and useful Improvements in Veneer Jointing andTaping Machines;'and I do i j I hereby declare the following to be afull,

clear, and exact description of the same, refcrence being had to theaccompanying drawings, forming a part of this specification, and't'o thereference-numerals marked theren On; I

My present invention has for its object to provide a' machine forjointing edge to edge two or more strips of veneer, during theirlongitudinal movement along a suit- 'able table or support, and it hasfor its further object the continuous applicationof a' binding tape tothe joint which will hold the parts perfectly united until they havebeen applied to the backing on which they even- I tually form thefinished surface.

To these and other ends the invention consi'sts in certain improvementsand combinations of parts, all as Wlll be heremafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings, Figure 1 is a side elevation of a machine constructedin accordance with my inventlon showin one embodiment Lthiareof; Fig; 2is a top p an view thereof;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2;Fig. 4 is a transverse sectional View taken'on the line a P of Fig. 3';Fig. 5 is a detail horizontal sec- 1 :tion'alv'iew illustrating themounting of the feed rollers, taken on the line 5 5 of Fig.- 4; Fig. 6is a detail view of the discharge rollers, taken on the line '6 6" ofFig. 1, and Fig. 7 is a detail illustration showingthe m'o'unting of oneof the feed rollers, said view being taken on the line 7 '7 x of Fig. l.Similar reference numerals throughout the several figures indicate thesame parts.

"The machine illustrated to show one embodiment of my invention,comprises generally a table or support upon which the strips of veneermay be positioned and provided with feeding mechanism which will advancesaid strips along the table and during their lengthwise movements willbring at I, HENRY RUNrTE, of

end of the machine is provided a pair of discharge rollers which may beactuated by the operator to withdraw the sets of united veneer sheetsafter-they have left the feeding mechanism at a more rapid rate oftravel, permitting them to be taken away from the machine and stacked bythe operator while the next pair of strips is being advanced by thefeeding mechanism.

The table or support 1 is mounted upon any suitable form of frame work,such as the uprights or table legs 2 which are connected at their lowerends by a rail 3. At about the center of the table and extendingtransversely thereof, are rollers 4i and 5, the

upper edges of which project slightly above.

the level of the table top and cooperate with the feeding and pressingrolls. ilhe feeding ,rolls' being those coiiperating with the roll 4 andthe pressing roll being the one indicated by 6 which bears against theroll 5, all of which are carried in suitable bearings.

Extending across the top cf the machine, is a framework supporting thefeeding rolls, comprising the vertical standards 7 and the cross bar 8on the forward edge of which. at the center of the table, are mountedtwo pairs of feeding rolls bearing against the roller 4. One pair ofthese rolls indicated by 9,

is disposed centrally of the table and each of them is set with its axisat an angle to the other and at angle to the agms of the underlying feedroller 4. These rolls being also positioned at'opposite sides of the henter line of feed whereby each operates upon a difi eren't strip ofveneer, they will more said'strip's lally toward each other. The

other pair of rollers indicated by W are disposed one on each side ofthe first mentioned pair and are adjustable, These pairs of rollers areshown in detail in Figs. 3, 4.- and 5. The rolls 9 preferably maintain agiven angular position to the direction of movement of the work pieces,each of said rolls being carried in a yoke piece 11 on a verticalbearing pin 12 (Fig. 5) restin in an aperture in'the upright frontportion 13 of the cross piece support 8 and against whi h bears a coilspring 14:. The desired angularity or convergence of the rollers 9 ismaintained by connecting the yoke 11 by two fastening members 15 and 16,having angular faces, as shown in Fig. 5, and fitted to the sides ofsaid yokes, to which they are 15 also'secured by bolts 17. The otherrollers .10 are each carried in yokes 18 on studs 19 projecting upwardlyinto bearingapertures in side pieces 20, containing coil springs 21.,the tension of which may be adjusted by screws 22. Extending laterallyfrom the yokes 18 are short projections 23, pivotally connected toadjusting arms 24, carried on screws 25, extending upwardly through theframe piece 8 and movable in one direction 0 or the other in slots 26(Fig. 2) for the pur- :pose of rotating the yoke18 in one direction orthe other relatively to the movement of the veneer strips. The tapefeeding and applying mechanism is also carried on the cross frame ormember 8 and is so arranged as to enable the tape to be appliedcontinuously to the veneer strips as these are brought together bythe-pairs of feeding rolls 9-9 and 1010. On the'front of the frame piece8 and extending downwardly between and slightly ahead of the diagonallydisposed rollers 9-9 is a sprin operated rubbin finger 27, having thelower narrow roun ed end 28 adapted to rest against the veneer sheets,and at its upper end, where its width is increased, it is ro- 'videdwith the parallel side edges 29, which are guided between theforwardlyextending ears or'projections 30 -30, on the forward clampinstri 15, which latter, it' will :be remembers is ascribed as beingcarried onthe yokes '11 of the rollers 99. The lateral edges oftherubbing fingers'serve as shoulders against which leaf springs 31'engage to normally force it downwardly. On the face' of the rubbing fingvided adjustable guides 32, held in position by the thumb screws 33 bymeans of which said guides may beadjusted relatively to the center lineof the finger to accommodate -.bindin tapes of different widths.-

Bin 'ng strips which I deem it preferable to use are made of stout aperhaving a gummed surface but it being understood that an ungummed stripof paper or fabric to which glue or paste is applied from a suitablereceptacle may also be used. However when a gummed strip is employed itis merely necessary to moisten the latter and the required quantity ofwater for this purapparatus for accomplishing this purpose,

or are also propose may be supplied from a suitable receptacle indicatedby 34-, having liquid supply rolls 35, 36 and 37, although it will beunderstood of course, that other forms of may be employed. The strip oftape is supplied from the roll 38 and in the present instance is shownas passing over the idlers 39, 40 and 41.

The advance movement of the work pieces or veneer strips is caused bythe feed rollers 4, 9 and 10 and 5 and 6. The rollers -land 5. arepositively driven, while the roller 6 which is a pressure roller iscarried in bear.- ings, which are moved downwardly by coil springs 42.On the rear side of the machine the roller 5 is provided with thedriving pulley 5 carrying the belt 5 which is driven from a pulley onthe shaft 43. The feeding'roll 4 is driven from the roll 5 by 35 a belt5. Another feeding roll is also provided to bear upon the top of theveneer strip and to assist in pressing the tape into intimate contactwith the veneers after they leave the aforedescribed rolls. Thispressing on and feeding roll, shown articularly, in Figs-2 and 3 andindicated by 44 is felt covered and provided with a sand surface whichwill afi'ord suflicient traction to en-- able'the veneer strips to beadvanced alongv e5 the table after their ends leave the feed rolls 5 and6. This roll 44 is carried onthe shaft 45 driven by a belt 45' from apulley on the roll 4.

When it. is desired .to. rotate the pulley 5 and im art movement to thefeed roll, the belt 5 15 tightened by bringing into contact with itslower stretch, the tightener pulley 5, held on the pivoted arm 46 whichmay be raised and lowered by a cam 47, rotated in any convenient manner,as by means of a lever 48. The pressing of the gummed strip intoengagement with the veneer strips-vie also facilitated by a pressureroll 49 arranged directly in rear of the roller 6 which is operateddownwardly by a spring 50 engaging the vertically movable framework inwhich said roll is placed.

At the rear end of the machine is a pair of rollers 51 and 52, theformer bein stationarily supported in bearings 53 an earrying a pulley54, driven by the belt 54 which also passes over a pulley 55 arrangedconcentrically to the pulley 5. The other roller 52 is mounted inbearings 52 which are guided for vertical movement 'on the rear uprightsor legs 2 of the frame and adapted to be operated toward and from theroller 51 by a lever 56, pivoted at 57 and operated by a rod 59 which inturn is connected to the treadle 60. Ooiiperating with the latch 59 is alock 61 having a shoulder engaging over the top of the treadle when thelatter is depressed. Movement of the treadle in a downward directionwill'permit it to be no locked bythe latch or awl 61 at which time theroller 52 is in an e evated position, forcing the veneer strips againstthe roller 51.

It will be'observed from the relative sizes and 6.

In order to facilitate assembling the work pieces and bringing them intojuxtaposition centrally upon the table in proper relationship to thefeeding rolls 99 and 10-10, 1

insert in the center of the table top two or" more blades such as areindicated by 62,

- which are preferably made of thin sheet metal, their opposite sidesserving as guides for the edges of two veneer sheets and permitting themto be brought closely together.

The thin sheets of veneer are usually warped and twisted and for thisreason their outer edges frequently have a tendency to curl after theirmeeting edges have been secured by the tape, and for this reason llprovide at the rear end of the machine over- I lying cover plates orguards 63, which hold the outer edges of the strips, or work pieces inproximity to the top of the table after they have passed between thepressing rolls 5 and 6, thus preventing said edges from curling upwardlyand engaging other parts of the machine, such as the shaft bearing thefeed roller 44.

In the operation of the machine, the binding strip is first positionedas shown in Fig. 3, its lower end, after passing over the various idlersand the moistening roll-37, ex-

tending beneath the rounded end 28 of the pressing finger 27. Themeeting edges of the veneer strips which are to be jointed, are firstmade true and straight by passing them in engagement with the cutter ofa jointer or other suitable machine. Two sheets of veneer thus preparedare then placed on the table at opposite sides of the center guides 62,their forward adjacent v corners being brought closely together and heldin this position by the operator while I they are advanced forwardlyinto engagement with the roller 4 and the pairs of roll ers 99 and10-10. The guide 62 located nearest the pressing finger is arranged atsuch a distance in rear thereof that the thin veneersmay easily be fedlaterally by the diagonal rolls 99 and brought into intimate contact atthe point where the tape is applied to the joint. Other guiding meansthan the blades 62 might be used or these might be omitted entirely, butI consider it an advantage to separate the rear ends of the veneer stris slightly, as the o erator is thus able to o serve the action 0 thefeed rolls and regulate pressure between the meeting edges of the veneerstrips more easily and accurately than can be done when the two stripsare put into the machine with their edges meeting throughout theirlength. The angularity of the rollers 9-9 is preferably fixed and whenarranged about as shown in Figs. 4 and 5 they will automati-' callymakeva close joint between two pieces of veneer .when these are handledin the manner described. When it is found that it is desirable to efiecta greater lateral movement of the sheets, this may be accomplished bythe adjustment of one or both of the rollers 10-10, the pressure ofwhich may be regulated by the screws 22 and their angularity changed bythe movement of the screw 25 and the slot 26 causing the arms 24 and 24to rotate the yokes 18 in one direction or the other to guide the sheetas a whole inwardly or outwardly relatively to the central line oftravel.

I claim as my invention:

1. In a veneer jointing machine, the combination with a support, of anunderlying feed roller and two separate pairs of rolls cooperating withsaid roller, the innermost rolls of each pair being set upon axes arranged at an angle to the axis of the underlying roller and theoutermost rollers of said pairs being mounted independently of the innerrolls so that their axesmay be shifted relatively to the axis of saidunderlying roller, and means for applying a binding strip to work piecesinserted between the feed roller and said rolls.

2. In a veneer jointing machine, the combination with a work table orsupport, of a feed roller arranged at one side of the plane of saidtable and two pairs of rolls cotiperating therewith and located at theother side of said plane, one of each pair of said rolls being arrangedon a fixed axis the as posed at an angle to the feed roller and theother one of each of said pairs being mounted so that its axis may beadjusted at a desired angle to the feed roller and means for applying towork pieces passed between said 1 tea a support arranged above thetable, of two angularly disposed rolls cotiperating with i the feedroller, said rolls being disposed centrally and spaced apart, two otherrolls arranged at each side of and mounted inclependently of those'firstmentioned and also cooperating with the feed roller and ad justablymounted on the bridge piece and a pressing finger yieldingly engagingveneer strips when placed with their meeting edges between the angularlydisposed rolls.
